Reading the OPN code on your AMD Athlon 64 to find out what CPU you have (for Athlon XP CPU's look here)

Overclockers.com dug a little deeper and found some valuable info about the OPN codes on A64 CPU's.

Here's the gist of the article using the CPU pictured below from JNav89GT:

ADA3200DIK4BI


Type of CPU: ADA3200DIK4BI

A = Athlon 64/FX
O = Opteron
S = Sempron


CPU purpose: ADA3200DIK4BI

D = Desktop
M = Mobile
S = Server


Wattage output: ADA3200DIK4BI

A = Desktop replacement (regular wattage)
N = 62 watt processor
D = 35 watt processor

Speed rating: ADA3200DIK4BI

- 4 numbers = A64 or Sempron
- 3 numbers = Opteron
- 2 letters (FX) / 2 numbers= Athlon FX


Socket: ADA3200DIK4BI

A = socket 754
C = socket 940
D = socket 939


Core voltage: ADA3200DIK4BI

E = 1.5V (130nm desktop cpu)
I = 1.4V (130nm mobile cpu or 90nm desktop cpu)
Q = 1.2V (mobile cpu)


Maximum Temperature: ADA3200DIK4BI

K = ??? (used so far on all 90nm CPU's)
O = 69C (Opterons)
P = 70C (130nm desktop CPU's)
X = 95C (mobile CPU's)


Cache: ADA3200DIK4BI

2 = 128K (some Sempron mobiles)
3 = 256K (Hammer based Semprons)
4 = 512K (Newcastle/Winchester-based Athlon 64's)
5 = 1Mb (Clawhammer-based A64s, FX's, and Opterons)


Stepping: ADA3200DIK4BI

AK = FX, CG
AP = A64, A64Mob, C0
AR = A64, A64Mob, CG
AS = FX, CG
AT = FX, CG
AW = A64, CG
AX = A64, A64Mob, Semp, CG
AY = AXP-M
BI = all 90nm CPU's (stepping of 90nm CPU's will start with B)

nice info

way more "overzichtelijk" then the overclockers article
